Note: Fits 2007-2012* JK Wrangler Dana 30 & Dana 44 axles. We recommend ball joints without knurls as they will not score the inner knuckle and open up the bore. We also offer ball joint with knurls for ball joints that have a loose press fit in the inner knuckle due to repeated ball joint replacement or if knurled ball joints have been installed in the past.
*SOME 2012 and ALL newer Jeep Wranglers come factory with larger front axle shafts (Dana 30 & 44) than previous years, and will require grinding on the stub shaft forging parting line for clearance.
